Hello! I'm new to this forum, I have never used a site like this before.
My family tried fostering dogs in 2013, and we ended up keeping three of the dogs we fostered. Two of these dogs have bum legs. One of them, Casper, is missing the joint in his wrist (his paw is just limp, no pain, just can't use it), and the other, Darby, had a broken leg that healed wrong. He walks with a constant limp, and while he is not in pain, too much activity causes his paw to hurt, and the way he walks on one of his pads causes it to open up and bleed. He can fetch about three times in the yard before he slows down.
Casper is probably about 10-15 lbs overweight, 85 lbs total. He's unpredictable and shocky, and because of this we have never been able to train him how to walk outside of the house (he can't stand being leashed or in a harness). On a good day I can walk him in the back yard, but I'm not sure how long to walk with him because of his leg.
Darby is 65 lbs, and he is probably also about 10 or 15 lbs overweight. He walks on a leash alright but walking on pavement for too long can cause his pad on his paw to start bleeding again (he walks on it awkwardly because of the limp).
We have cut all our dogs back on food, giving them all the suggested amount on the bag (dry food). I break their treats apart, although other family members in the house don't. My mom also has a bad habit of sharing too many scraps.
I'm basically looking for suggestions on how to walk or exercise these two dogs, since clearly the food part of it alone is not cutting it. I need a way to exercise Casper without walking him outside - I'm not strong enough to force him out of the house or into a harness. I also need ideas for other exercises for Darby that aren't walking or running, since it makes his pad bleed. Any help would be greatly appreciated... I don't want them to be sore when they get older because of their weight!
PS Casper is 5 1/2 years old, Darby is 5.
